FREDERIC E. BERTRAND, OF LYNN, MASSACHUSETTS, ASSIGNOR T(.')` UIN'ITIE}IVJV SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, AkCORPORATION 0F NEW JERSEY.

To all whom t may concern Be it known that I, FREDERIC E. BERTRAND, acitizen of the United States, residing at Lynn, in the county of Essexand State of 5 Massachusetts, have invented certain new and usefulimprovements in Thread--Waxing' Devicesgand I do hereby declare thefollowing to be a full, clear, and exacty description of the inventionsuch as will enable others skilled in the art to which it appertains tomake and use the same.

VThis invention relates to threadwaxing devices for sewing machines. Thewax ordinarily employed in waxing sewing thread, which ,is solid` atordinary temperatures and is reduced to a fluid state by the applicationofvheat thereto before it is applied to the thread, deteriorates rapidlyin qualityv when maintained at the high temperature required to enablethe wax to permeate properly the thread. In thread waxing devices inwhich a relatively large perature for a longtime, much of the waxdeteriorates in quality before it is used.

One of the principal objects of the present invention is to produce athread waxing 'device of novel and improved construction in which suchdeterioration in the quality of the wax will be avoided. Y `With thisobject ,in view an importan feature of t-he invention consists in the,provision of an atmospheric pressure controlled or so-called barometricfeeding reservoir arranged to supply wax to the chamber or receptacle inwhich the wax is applied to the thread. Such an arrangement .permits theuse of a receptacle of relativelysmall capacity in which the'wax isapplied to the thread and a reservoir of relatively large capacityforreplenishing the'supply inthe waxing receptacle. The heating devicesare ar-V ranged tovheat theiwax in Vthe receptacle to a relatively highVtemperature to, maintain the same inproper condition to Vbeyapplied tothe thread and to heat the wax in the reservoir toa relatively lowtemperature so as to melt the same gradually as vrequired to replenishthe wax in the receptacle;

Another feature of the invention contemplates the provision of means forremovably supporting a supply reservoir in operating position withrelation to the thread waxing chamber so that the reservoir may be reeATHREAD-VJAXING DEVICE.

inf operating position with relation to the re- A Vceptacle, the lotherconstitutes a reserve reservoir whichmay be used when the wax in the rstreservoir is exhausted.

Still. another feature of the invention contemplates the provision ofsupporting dep' vices for the reservoirs of such construction Vandarrangement that when one reservolr 1s Y in operating position, thereserve reservoir receives a certain amount of heat from ,the heatingldevices so that. it is ready for immediate use whenthe wax inthe rstreser- Y voir is exhausted. body of wax is maintained at a high tem-Other objects of the invention are to improve the construction and modeof operation of thread .waxing devices` andto produce a thread waxingdevice in which the supply of wax may be much more easily andconveniently renewed than in such devices heretofore constructed.

y In the present construction the supply reservoir comprises a supportor holder especially constructed to'receive cartons of paper orcardboardfilled with hard wax. In order to Arender the cartons unfit tobe i used again, means is provided for mutilat-y ing the cartons. lToinsure the mutilation means is actuated to mutilate the same. v

Otherv features ofthe invention consist 'in certain novel and improvedconstructions and combinations of parts hereinafter described andparticularly pointed out in the f claims the advantages of which will beunderstood' `and appreciated by those skilled in the art. l

The various'` features of the invention will ,be readily understood from,the accompanying drawings illustrating the invention in its`preferredform, and the following detailed description. of theconstructions there in shown; l.

In the drawings Figure l is a planview of a thread waxingdevieeembedying the invention; Fig. 2 is' a view ofthe device partly infront elevation and partly in section on the line 2-2 of Fig. l; Fig., 3is a viewin sideelevation of the device; Fig. 4 is a sectional view ofthe device taken substantially on the line fil- 4 of Fig. l; Fig.

is a fragmentary sectional view .taken on the line 5 5 of Fig. l; and'Figi. 6 is a fragmentary sectional view taken on. the line 6'-l6`of Fig-5.' Y f 1 In the drawings the thread waxing'cham-V ber or receptaclethrough which the thread is passed on its way from the supply to thework is indicated at l0, and" consists of a shallow trough of relativelysmall 'capacity in which the wax is maintained' in a thoroughly meltedstate by theY heat' transmitted from a steam chamber l2 formed in thewall of the receptacle... Two wax supply reservoirs are illustrated inthe drawing, these reservoirs being indicated respectively at 14 and 16.Thesereservoirs are ol" the same construction and each Y.consists of a'support Vor" holder 18. formed its upper end with a 'relatively largerecess or chamber and a passagefway leading downwardly from sai-dchamber "through a discharge nozzle 2O formed at the lower vend ot' theholder, and

' a carton., 22 mounted in the chamber in the upper portion of theholder.'E rlhe carton is closed at its upper end and is open at itslower endand is preferably constructed of heavy paper or cardboard. Theholders 18 are eachprovided' with a hingedcover 24'ar- .ranged to engagethe upper end of the carwhich. the nozzles of the supply reservoirsVarey inserted.. As illustratedin the drawing Vthe reservoir Tiflislocated: in operatingpo Ysiti'on in communication with f the threadwaxing chamber; l0, while the. reservoir. 1.6 is located.iniinopera-tive position out Ofcom? munication with said. chamber. andoonstitutesa reserve reservoir. The body 'ofthe holder 18 or.the,reservoinwhich isin posi tionto supply wax to thechamber, l0,.1restson the slide26 and the nozzle ot the reservoinextends .throughone of theopenings 32 inl thersli'de andthrough the corresponding opening 34,in,the shelfl 28;'and. projects slightly;intov the. chamber. V1.() sovthat. the opening atthe. lower end thereofis sealed vor covered..by the.melted wax. inisaid. chamber when the; chamber isfilled withwax. The

nozzle oi" the reserve reservoir is inserted in the other opening 32 inthe slide 26andy rests upon the shelf 28, which supports the reservoirwith the body of the holder '18 out of contact with the slide, and alsocloses the lower end of the nozzle, thereby preventing the wax in thereserve reservoir from being discharged through the.V nozzle'.

In order that the carton 22 aridiY theholder i 18 when associated may beemployed as barometricV Jfeeding reservoir, provision isV made forforming'lan air-tight joint between the open end of the vcarton and theholder. This .is accomplished by prviding an interior' shoulder 36yhaving a tapering surface at the lo-wer portion otI the body of theholder upon which the open endV of the carton may rest. lVhen the cover24%l isv closed the carton is pressed li'rmly against .the taperingsurfaceV of the shoulder so that air is prevented from entering` thereservoir en# cept through thenozzle 20. The wax in the reservoir isltept at theA proper temperature by means of a steam chamber 38 formedin the frame of the device adjacent the slid'e'26 rfhe heattransmittedhfrom the steam chamber 38 issuilicient to maintain Vthe waxin a fluid condition in the nozzle and lower portion of therreservoirwhich is in use. As

long as the supply of wax in the chamber 10 is above the lower endof thenozzle' oft this reservoir yit closes the opening in the nozzle J.against the entrance of air, and no wax willV flow from;thereservoir'into the chamber 10.V

As thewar; iny they chamber 10 is used up to the pointwhere its surfacefalls below the lower end' of the nozzle, air is permitted to y enterthe reservoir andthe wax will How 'from the reservoir into the chamberl0 until the lower end ot thel nozzle is again closed.

In this way a substantially uniform quantity of waX is maintained inIthe-thread waxingchamber. The wax in the upper part of the reservoir issoftened somewhat Aby the heat transmittedv thereto, andjwill 'flowgradually downward to thenozzleoi the reservoir as vthe waxisdischargedthrough the nozzle- The reserve reservoir becomes heated to arelatively slightdegree inasmuch as the body of the holder 18 of the.reserve res ervoii` held out ot contact with the slide 1 2,6 through theengagement of the lowreri end Y .when ythe warn-in thef-rese'rvoir whichis being lusedis exhausted.v In replacing anerrhausted reservoir with areserve reservoir, the

former is lifted sufficiently to raise the nozzle 20 of said reservoirabove the surface of the shelf 28, and the slide 2 6 is thenshifted tobring the reserve reservoirinto position for the insertion of the lowerend of the nozzle through the opening 34 in the shelf. lt will beapparent that the slide 26 islocked in position on the shelf 28 wheneither of the reservoirs is in operating position by the engagement ofthe nozzle ofthe active reservoir in the respective openings in theslide l and shelf.

With a thread waxing device of the above construction. only a relativelysmall quantity of wax is heated toa high temperature at any time, themain body of the wax in the device being kept relatively cool. l kThewaX, therefore, is maintained at ahigh temperature for only a short timebefore it is applied to the thread, and consequent deterioration of thewaxis avoided. ,Y

It may be desirable for certainreasons to prevent. the cartons employedin the present device, after having been used, from being refilled and.used again` and kto this end means is provided for mutilating thecartons before they are removed fromY the device. In the presentconstructionthe mutilating means comprises a punch 4Q which` is carriedby the cover 24 and is; arranged to be projected through a slot 42 inthe holder 1 8 into the carton near the closed end thereof before theremoval of the Acarton from the holder. In order to insurev that thepunch will be inserted in the carton before the carton is removed fromthe holder, a latch 44 is provided for latching the` cover in closedposition, which is arranged to be released by the mechanism forVactuating the punch and cannot be released without first actuating thepunch.A The latch is mounted to slide in the cover 24 and is arranged toengage at its forward end beneath one or more shoulders 46 formed on theholder 18. The latch is arranged to be projected into latching positionby means of a coiled spring .on a stud 76 mounted on a depending por*48. The punch 40V is carried by an arm 50 fixed to one end of a slidebar 52 mounted to slide longitudinally through a bearing in the cover.The opposite end of the slide bar 52 is pivotally connectedat 54 with ahandle 56. The handle 56 and 'the cover 24 are both lpivoted on theholder 18 by means of a pin 58, and the hand-le is Vconnected with thecover 24 by means of a` spring The spring 60 tends to pull the handle56toward Vthe cover, thereby holding the slide bar 52 in the positionshown inf'Fig. 5, with the punch 40 clear of the carton. The means forreleasing the latch 44 consists of a lug 62 mounted on the punchcarrying arm 5,0, which is arranged to be projected through the slot 42so as to engage the forward end of the latch just before the punchreaches thel limit of its inward movement,- and Vof the melted wax.

leaseY of the latch the cover is swung upwardly by the continuedmovement. of the handle 56. The punch 40 is swung upwardly with thecover by the action of the spring 60 and the carton is raised sov thatit project-s above the holder 18 and may be easily grasped by theoperator and removed from the holder.

When a'carton full of wax is insertedin the holder 18 and the cover .isswung into .closed position, the cover engages the upper end of thecarton and forces the same downwardly, therebvjpressing the lower end'ofthe carton firmly against the shoulder 36 on the holder to form an airtight joint be` tween the lower end of the carton andthe holder. In theillustrated construction the under side of the cover is so shaped as toenter into the top of thev holder 18, asvclearly shown in.. Figs. 2 and6. Y Y V The thread. `guiding and stripping means comprises ay pulley 64and astripping device 66, both of which are carried by an arm 68pivotally mounted on a shaft, 70, supported yby projections 72 and 74formed on the side ofthe receptacle l0. VThe arm 68 is arranged'V to benormally supported lon the shaft `with the thread guide and strippingdevice in their opera-tive positions, as shown in full lines in Fig. 4,and is adapted to be swung upwardly and supportedin the position shownin dotted lines in said figure so that the` parts may be easilyaccessible for the -purpose of threading.

The thread guiding pulley 64 is journaled tion of the arm 68. and vwhenin its normal or operative position the vpulley islo'cated adjacent thebottom of the thread waxing chamber l0, and close to the steam chamberVl2 where it is in'imersed in the hottest part The thread in its pas-Vsage tl'irough' the thread waxing chamber extends downwardly through apassage 78 in therarm 68, thence under the pulley 64 and upwardlythroughV the `stripping device 66. y

The stripping device comprises theusual rubber stripper block 8O whichis provided with an 'axial passage forI the thread. -The stripper blockis held in a cup 82jprovided with la hollow stem 84 which is secured bymeans of a set screw in a socket formed in lthe a'rm 68.V The cup 82islexternally t'iiretttiti it the top te; receive t @epee and afolloiv'er plate 88v is interposed between the Cap and the strippenlol'oel'.
